LG and KAIST Develop Advanced Lithium-Metal Battery for Electric Vehicles
LG Energy Solution and KAIST jointly
developed foundational technology for lithium-metal batteries, aiming to extend
the driving range by about 50% and significantly improve charging efficiency
and lifespan compared to lithium-ion batteries.
The existing lithium-metal batteries have
been criticized for limitations such as the threat to battery lifespan and
safety due to the occurrence of dendrites on the cathode surface and continuous
corrosion caused by the liquid electrolyte.
The research team successfully addressed
the limitations of traditional lithium-metal batteries by introducing a
groundbreaking 'borate-pyran-based liquid electrolyte,' enhancing charging
efficiency, and achieving a high energy density for a 900km driving range on a
single charge.
In addition, the team emphasized that the technology ensures stability with
over 400 recharge cycles, allowing for a simplified battery system design to
enhance the driving range of electric vehicles.
